**** SECTION 3 - HAZARDS IDENTIFICATION ****

EMERGENCY OVERVIEW
Contact with water liberates extremely flammable
gases.Water-reactive.

Potential Health Effects
Eye:
May cause eye irritation and possible burns.
Skin:
May cause severe skin irritation with possible burns, especially if
skin is wet or moist.
Ingestion:
May cause severe gastrointestinal tract irritation with nausea,
vomiting and possible burns.
Inhalation:
May cause severe irritation of the respiratory tract with possible
burns.
Chronic:
None

**** SECTION 4 - FIRST AID MEASURES ****

Eyes:
Flush eyes with plenty of water for at least 15 minutes,
occasionally lifting the upper and lower eyelids. Get medical aid.
Skin:
Get medical aid. Flush skin with plenty of water for at least 15
minutes while removing contaminated clothing and shoes. Wash clothing
before reuse. Destroy contaminated shoes.
Ingestion:
Never give anything by mouth to an unconscious person. Get medical
aid. Do NOT induce vomiting. If conscious and alert, rinse mouth and
drink 2-4 cupfuls of milk or water. Wash mouth out with water.
Inhalation:
Remove from exposure and move to fresh air immediately. If not
breathing, give artificial respiration. If breathing is difficult,
give oxygen. Get medical aid.
Notes to Physician:

**** SECTION 5 - FIRE FIGHTING MEASURES ****

General Information:
As in any fire, wear a self-contained breathing apparatus in
pressure-demand, MSHA/NIOSH (approved or equivalent), and full
protective gear. Water Reactive. Material will react with water and
may release a flammable and/or toxic gas. Containers may explode in
the heat of a fire. May re-ignite after fire is extinguished.
Extinguishing Media:
Do NOT get water inside containers. Cool containers with flooding
quantities of water until well after fire is out. DO NOT USE WATER
OR FOAM. For small fires, use dry chemical, soda ash, lime or sand.
For large fires, use dry sand, dry chemical, soda ash or lime or
withdraw from area and let fire burn.

**** SECTION 6 - ACCIDENTAL RELEASE MEASURES ****

General Information: Use proper personal protective equipment as indicated
in Section 8.
Spills/Leaks:
Absorb spill with inert material (e.g. vermiculite, sand or earth),
then place in suitable container. Provide ventilation. Do not expose
spill to water. Do not get water inside containers.

**** SECTION 7 - HANDLING and STORAGE ****

Handling:
Avoid breathing dust, vapor, mist, or gas. Avoid contact with skin
and eyes. Do not allow contact with water. Use only in a chemical
fume hood.
Storage:
Keep away from sources of ignition. Store in a cool, dry place.
Store in a tightly closed container. Water free area. Store totally
immersed in oil.

**** SECTION 8 - EXPOSURE CONTROLS, PERSONAL PROTECTION ****

Engineering Controls:
Use adequate ventilation to keep airborne concentrations low.
Exposure Limits

CAS# 8042-47-5:


Personal Protective Equipment

Eyes:
Wear appropriate protective eyeglasses or chemical
safety goggles as described by OSHA's eye and face
protection regulations in 29 CFR 1910.133 or European
Standard EN166.
Skin:
Wear appropriate protective gloves to prevent skin
exposure.
Clothing:
Wear appropriate protective clothing to prevent skin
exposure.
Respirators:
Follow the OSHA respirator regulations found in 29
CFR 1910.134 or European Standard EN 149. Use a
NIOSH/MSHA or European Standard EN 149 approved
respirator if exposure limits are exceeded or if
irritation or other symptoms are experienced.
